AB  - In the present work, a simple and effective method based on magnetic separation 
      has been developed for the extraction of monocyclic aromatic amines in water and 
      urine samples using poly(para-phenylenediamine) modified with Fe3O4 nanoparticles 
      (PpPD/Fe3O4) as an adsorbent. The chemical structures of the sorbent were 
      characterized by field emission scanning electron microscopy (FESEM) and Fourier 
      transform infrared spectrophotometer (FT-IR). Various parameters affecting on the 
      extraction efficiency of desired analytes, such as pH of solution, desorption 
      conditions, extraction time, salt effect and amount of adsorbent have been 
      investigated and optimized. The obtained optimal conditions were: sample pH, 6; 
      amount of sorbent, 20mg; sorption time, 2min; elution solvent and its volume, 
      dichloromethane and chloroform (3:1 v/v), 250muL; elution time, 30s and without 
      addition of NaCl. Under the optimum conditions, detection limits in the range of 
      0.007-0.01ngmL(-1) were obtained by gas chromatography-flame ionization detector 
      (GC-FID). The calibration curves were linear in the range 0.05-100ngmL(-1) with a 
      correlation coefficient better than 0.9953. In addition, a satisfactory 
      reproducibility was achieved by evaluating the intra- and inter-day precisions 
      with relative standard deviations (RSDs) less than 5.9 and 7.3%, respectively. 
      The proposed procedure has been successfully applied to the determination of 
      target analytes in water and urine samples. The results demonstrated that the 
      developed method is simple, inexpensive, accurate and remarkably free from 
      interference effects.
